LINER FOR CENTRIFUGAL LlQUlD-SEPARATORS.

SPECIFICATION forming part of Letters Patent No. 767,519, dated August 16, 1904.

Application filed February 26, 1904. Serial No. 195,349. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES H. HACKETT, a citizen of the United States of America, and a resident of Vaterloo, Blackhawk county, Iowa, have invented, certain new and useful Improvements in Liners for Centrifugal Liquid-Separators, of which the following is a specification.

My invention relates to improvements in liners for centrifugal liquid-separators; and the object of my improvement is to so construct such liners as have concentric layers of separating-disks in inner and outer series as to secure more perfect action by increasing the resistance offered to the passage of the liquid over them. This is effected by spacing the outer disks closer together than the inner disks. This objectI have effected by the means which I hereinafter describe and claim and which are illustrated by the drawings hereto annexed, in which Figure 1 is a vertical sectional view of a two-series disk liner on the line .2 z of Fig. 2; and Fig. 2 is a sectional plan view, with parts broken away, on the line w m of Fig. 1; and Fig. 3 shows part of two disks of a singllfi-series liner, said disks spaced apart varia y.

Similar letters refer to similar parts throughout the several views.

In liners having inner and outer series of concentric separating-disks the disks of the separate series are spaced the same distance apart. As it has been found desirable to progressively increase the resistance to the passage of liquid outward from the axis of the bowl while under the influence of centrifugal action, I have accomplished that end in the design of a multiple-series liner by placing a greater number of disks at a less distance apart in the outer series than is the case with the inner series. I

In the liner illustrated the outer and inner series of disks (4 and 6, respectively, are employed. The outer series a are supported by the uprights f, and its disks a are inclined downward toward the axis of the bowl.

IVhile I have illustrated a multiple-series liner, my said invention also comprehends liners having a single series of disks wherein the spaces between the disks are progressively widened in a direction from outward toward the axis of the bowl. The Widening of the spaces assists the inward. movement of the lighter constituent of the liquid. This is done by thickening the disks 6 outwardly, as in Fig. 3.

The uprights f are attached to a top ring d and a bottom plate It. The inner series of disks Z) are supported by uprights e, the latter being attached to a top plate 0 and a bottom plate 9. The inner series of disks 6 is inclined downward from the axis of the bowl outwardly. An exit-tube 70 for the escape of the lighter constituent of the liquid is attached to the inner part of the inner series of disks, as shown. The inner series of disks Z) is separable from the outer series of disks a and when placed'within the latter is kept in the same relative position by means of the studs z'passing upward from the plate It through holes in the bottom plate g.

In the case of the liner illustrated the.

numbers of disks in the inner series 6 and the outer series a are thirty-two and forty, respectively; but the particular numbers in either series is not material, provided that the number of disks in the outer series is greater than that in the inner series and is spaced a less distance apart. The result of spacing the disks in the outer series a less distance apart and using more disks in that series is to add to the number of surfaces opposing a frictional resistance to the outward passage of the liquid while under the influence of centrifugal action. When used to separate liquids containing a light and a heavy constituent, such as milk, the partially-separated milk which issues from the spaces between the disks of the inner series comes in contact with the more numerous disks of the outer series and its motion is considerably retarded. The consequence is that the smallest globules of the cream are afforded more opportunity to separate from the heavier watery element on account of the increased fric- Eli consisting of inner and outer series of concentric separating-disks, the inner series being separable from the outer series, and the number of disks in the outer series being greater and spaced nearer together than are the disks in the said inner series, substantially as shown and described.
